The British government will on Monday seek to overturn a ruling that it must obtain parliamentary approval before triggering Brexit, in a highly-charged case in Britain’s highest court.

UPDATE 1620 GMT – For the confused, here’s how the Supreme Court judges are actually chosen

The UK Supreme Court is a new invention, having only existed since 2009 after being established by the 2005 Constitutional Reform Act.

Before then, Britain’s most senior judges sat in the House of Lords, where they were known as Lords of Appeal in Ordinary (or “Law Lords” for short). All judges appointed to the court are still awarded peerages, although they are not allowed to sit or vote in the House of Lords during their tenure.

New appointments are not subject to anywhere near the same scrutiny as U.S. Supreme Court justices, facing no questioning or confirmation vote by any elected body.

Instead, they are chosen by a Selection Commission, headed by the current President of the court, alongside another senior judge and representatives from the judiciaries of England and Wales, Scotland, and Northern Ireland.

The court is therefore selected largely by the legal establishment, with public scrutiny over appointments near impossible, especially as it does not even publish the Selection Commission’s deliberations.

UPDATE 1450 GMT – ‘Euro Act Does Not Remove Royal Prerogative’

Government QC James Eadie has continued his case, saying that the European Communities Act 1972, which took Britain into what was then the EEC, did not restrict the government’s ability to invoke the Royal Prerogative to take Britain back out again.

However, in response the judges have asked why if joining the EEC was a joint effort between Parliament and the executive, leaving cannot be.

This is without a doubt the biggest UK court case to ever be televised.

TV cameras, photographers and audio recording are traditionally not allowed inside UK courts. This case is a rare exception.

UPDATE: 1215 GMT – ‘Government has right to trigger Article 50’

Also speaking for the government, James Eadie QC said the prerogative powers that the government hopes to use are “a long-standing, well-recognised set of powers firmly established in our constitutional arrangements” that are “fundamental to our constitution and essential to effective government”.

Representing the British government, Attorney General Jeremy Wright said the High Court made the wrong decision.

He said that parliament will have already been “fully and consciously involved” when the government triggers Article 50, and that the government’s use of the Royal Prerogative will therefore be lawful.

He added there was “great constitutional significance in which there is understandable and legitimate interest both inside and outside this courtroom”.

The High Court ruled last month that the government did not have the executive power alone to invoke Article 50 of the European Union’s Lisbon Treaty, formally starting the exit negotiation process.

The decision enraged Brexit supporters and some newspapers who accused judges of thwarting the will of the 52 percent who voted “Leave” in a June 23 referendum.

A parliamentary vote on Article 50 could open the door to pro-Europe lawmakers delaying or softening Britain’s withdrawal from the bloc.

May’s government will set out its case Monday in an appeal of the High Court decision, with a verdict expected in January.

Attorney General Jeremy Wright, the government’s chief legal advisor, will argue that the government has constitutional authority over foreign affairs, including the right to withdraw from treaties, under so-called “royal prerogative powers”.

– Referendum a ‘footnote’ –

In papers submitted to the Supreme Court ahead of the hearing, Wright said High Court judges were “wrong to relegate, almost to a footnote, the outcome of the referendum”.

Claimants in the case, led by investment fund manager Gina Miller, argue that triggering Article 50 would strip British citizens of certain rights established under European law — which they say only parliament has the power to do.

Britain’s foreign minister, Boris Johnson, voiced confidence in the government’s case Sunday, telling the BBC’s Andrew Marr Show: “There is no history in any EU negotiations or any EU treaty talks of the House of Commons doing anything to fetter the discretion of the government.”

However, legal expert Michael Zander, a professor at the London School of Economics and Political Science (LSE), said the government had little chance of winning, describing the original ruling as “unanimous and very strong”.

“In my view, the government could be looking at losing 11-0,” he wrote in legal magazine Counsel.

– Timetable at risk –

If it does lose, the government is expected to introduce a short bill — reportedly comprising just three lines of text — which it will seek to push rapidly through parliament to authorise the triggering of Article 50.

May has insisted a parliamentary vote on the legislation would not disrupt her plans to trigger Article 50 by the end of March 2017.

However, the opposition Labour Party delivered a blow to the government Saturday when it announced it would seek to amend any bill, potentially delaying the process.

Labour leader Jeremy Corbyn said the amendment would ensure that Britain retains access to the European single market and protect workers’ and environmental rights.

“When the Article 50 debate comes up, we will put forward an amendment to it, which will be on the issues of market access and protections. We want those to be part of the negotiation,” Corbyn told Sky News.

He denied that the party was seeking to prevent the government invoking Article 50 altogether, adding: “We are respecting the result of the referendum. It might not be the one we wanted but it’s the one we’ve got.”

A spokesman for May’s Conservative Party accused Labour of attempting to “frustrate the will of the British people by slowing down the process… and trying to tie the government’s hands” in Brexit negotiations.

May faces a further potential complication at this week’s hearing from representatives of Scotland, Wales and Northern Ireland who will argue that Article 50 also needs to be approved by the devolved parliaments.

Such a ruling could further derail the prime minister’s timetable and set up a stand-off between the nations.
